What is preharvest factor?
Pre-harvest factors viz, environmental factors such as temperature, relative humidity, water potential, light, cultural practices and pest management techniques determined the inherent quality of the produce.
What factors affect fruit quality?
The type of root stock, the age of trees , the type of soil, cultural treatment, the kind and variety of plant, the season of harvest, etc. also influence the storage quality of the fruits to a certain degree.
What are the factors responsible for post-harvest losses in fruits?
In general, post-harvest losses of fruits and vegetables is influence by many factors. These factors includes losses due to physical, physiological, mechanical and hygienic conditions. Fruits and vegetables are mainly characterized by high level metabolic activities and known to posse’s short shelf life.
What is the importance of preharvest modifiers of quality?
3 Main Reasons: to prevent or correct minor element deficiencies with nutritional sprays as part of the mineral nutrition program. to control diseases, insects and mites with pesticides.
What influences pre-harvest on fruit and vegetables?
The pre-harvest factors influencing postharvest quality are frequency of irrigation, use of fertilizers, pest control, growth regulators, climatic conditions like wet and windy weather, natural climates such as hailing, high wind velocity, heavy rainfall, and tree conditions (age, training pruning, light penetration.
What is preharvest vegetable production?
Preharvest refers to activities on the farm or ranch that occur before crop or livestock products are sold.
What does preharvest in vegetable production mean?
What are the types and major causes of post-harvest losses?
Mainly, during retailing, rotting, mechanical damage, poor handling, improper management of temperature and relative humidity, and hygiene problems during handling are among the major causes of postharvest losses.
What are the causes of postharvest losses of fresh fruits and vegetables?
Common causes of postharvest losses are diverse, but the most common are overripening, disease, harvesting when the fruit is too immature, and mechanical damage. Studies of postharvest losses of vegetables identified losses in the range of 20 to 40%. Cabbage losses were amongst the highest, at 20 to 30%.
What does preharvest in vegetable production means?
What are the factors affecting the fruit cultivation?
Post-harvest life of fruits and vegetables is governed by water content, respiratory rate, ethylene production, endogenous plant hormones, and exogenous factors such as microbial growth, temperature, relative humidity and atmospheric compositions.
What is the importance of preharvest operations?
Pre-harvest production practices are critical in developing optimal quality of vegetable crops, which depends on the interaction of genetic, agronomic, and environmental factors.
How is fruit quality determined?
The internal quality mainly is determined by aroma, flavour, taste, texture, nutritional quality (e.g. soluble sugar content, starch, organic acids, soluble solids content, carotenoids, total flavonoids, total phenolics, antioxidant activity, etc.), flesh firmness, diseases, and chemical residues.
How do you determine the quality of fruits?
Quality factors for fruits include the following— maturity, firmness, the uniformity of size and shape, the absence of defects, skin and flesh color. Many of the same quality factors are described for vegetables, with the addition of texture-related attributes such as turgidity, toughness, and tenderness.
What are the effects of post harvest losses?
Post-Harvest Loss (PHL) has potential effects on food security and nutrition through the four dimensions of food security: Availability, Access, Utilization and Stability. Reduced losses increase access and availability. Reduced on-farm losses help farmers by improving diet or providing higher incomes.
What are the effects of post-harvest losses?
What are the factors that affect harvesting?
While the major factor determining the time of harvest is the maturity of the crop, other factors such as weather, availability of harvest equipment, pickers, packing and storage facilities, and transport are important considerations.
What is pre and post-harvest?
It is widely recognized that there are several pre-harvest (genotype, growing environment, cultural practices, ripening stage, etc.) and post-harvest (harvesting, post-harvest treatments, packaging, storage, etc.)
